For this particular DAC you need at least 4 of them for balanced operation because it's a mono chip IIRC.
I did the same thing! DAC19DSP at first, and now the Ref 5 (original version). Both are great DACs!
btw .Sup, I 've seen you pair your ref5 with an spl auditor, do they pair well? in my case will be a phonitor and senn hd800 too...
thanks a lot .Sup!
Have you tried the newer DSPs in your Ref 5?
[size=x-small] Both have built in DSP-1 and 4 pcs PCM1704UK .
The SA-1 retains rich details and high clarity with its abundant music flavor with wide and deep sound stage . It is single-ended output.
The Reference 5.2 sound dead neutral and monitor . It is balance output.[/size]
What are the benefits of having 4 DAC chips? I can understand where having two would allow 1 to be used for left and 1 to be used for the right channel, but what are those other two chips doing? Just hanging out being cool until Quadraphonic systems catch on (remember those?)?
Slightly offtopic: do you know is it possible to connect balanced DAC (Reference 5.2) to a single-ended amp (C-2.1) via ACSS? Balanced/single-ended ACSS confuses me a bit...
I'm guessing Kingwa is using a pair of chips per channel so he can take the difference between them. This means one chip has 'true' data fed to it and the other has inverted. The idea behind such balanced operation is that things that affect both DAC chips equally (power supply noise for example) will get cancelled out in the subtraction stage.
I got a reply from Kingwa saying that his balanced DACs produced since 2012 can connect to single-ended amps via ACSS.
